【摘要】：微藻生物柴油是当前生物能源中最具发展潜力的一种新型能源,为更好地开发微藻生物柴油,筛选出适合制备生物柴油的富油微藻,以10种热带富油微藻为研究对象,对其生物量、总脂含量及脂肪酸组成进行分析。通过甲醇-氯仿(体积比为2∶1)称量法测定10种热带富油微藻中的总脂含量,将从微藻提取的油脂经过甲酯化反应后,采用气相色谱-质谱联用(GC-MS)分析油脂中脂肪酸组成及含量。结果表明,10种热带富油微藻中Chlorella vulgaris CJ15和Desmodesmus sp.WC08更适合制备生物柴油。
[Abstract]:Microalgae biodiesel is one of the most promising new energy sources. In order to develop microalgae biodiesel, oil-rich microalgae suitable for the preparation of biodiesel were selected. Ten species of tropical oil-rich microalgae were used as research objects. Its biomass, total lipid content and fatty acid composition were analyzed. The total lipid content of 10 species of tropical oil-rich microalgae was determined by the methanol-chloroform (volume ratio 2: 1) weighing method. The composition and content of fatty acids in oils were analyzed by GC-MS. The results showed that Chlorella vulgaris CJ15 and Desmodesmus sp.WC08 from 10 species of tropical oil-rich microalgae were more suitable for the preparation of biodiesel.
